Updated rule amends silica exposure regulations
for first time since 1971
WASHINGTON - The U.S. Department of Labor’s Occupational
Safety and Health Administration today announced a final rule to improve protections
for workers exposed to respirable silica dust. The rule will curb lung cancer,
silicosis, chronic obstructive pulmonary disease and kidney disease in America’s
workers by limiting their exposure to respirable crystalline silica.
“More than 80
years ago, Labor Secretary Frances Perkins identified silica dust as a deadly
hazard and called on employers to fully protect workers,” said U.S.
Secretary of Labor Thomas E. Perez. “This rule will save lives. It will enable workers to earn
a living without sacrificing their health. It builds upon decades of research
and a lengthy stakeholder engagement process – including the consideration of
thousands of public comments – to finally give workers the kind of protection
they deserve and that Frances Perkins had hoped for them.”
OSHA estimates that when the final rule on Occupational
Exposure to Respirable Crystalline Silica becomes fully effective, it will save
more than 600 lives annually and prevent more than 900 new cases of silicosis –
an incurable and progressive disease – each year. The agency also estimates the
final rule will provide net benefits of about $7.7 billion per year.
“The previous exposure limits were outdated and did not
adequately protect workers,” said Assistant Secretary of
Labor for Occupational Safety and Health Dr. David Michaels. “Limiting exposure to silica dust is essential.
Every year, many exposed workers not only lose their ability to work, but also
to breathe. Today, we are taking action to bring worker protections into the 21st
century in ways that are feasible and economical for employers to implement.”
About 2.3 million men and women face
exposure to respirable crystalline silica in their workplaces, including two
million construction workers who drill and cut silica-containing materials such
as concrete and stone, and 300,000 workers in operations such as brick
manufacturing, foundries and hydraulic fracturing. Most employers can limit
harmful dust exposure by using equipment that is widely available – generally
using water to keep dust from getting into the air or a ventilation system to capture
dust where it is created.
The
final rule will improve worker protection by:
- Reducing the permissible exposure limit for crystalline silica to 50 micrograms per cubic meter of air, averaged over an eight-hour shift.
- Requiring employers to use engineering controls (such as water or ventilation) and work practices to limit worker exposure; provide respiratory protection when controls are not able to limit exposures to the permissible level; limit access to high exposure areas; train workers; and provide medical exams to highly exposed workers.
- Providing greater certainty and ease of compliance to construction employers – including many small employers – by including a table of specified controls they can follow to be in compliance, without having to monitor exposures.
- Staggering compliance dates to ensure employers have sufficient time to meet the requirements, e.g., extra time for the hydraulic fracturing (fracking) industry to install new engineering controls and for all general industry employers to offer medical surveillance to employees exposed between the PEL and 50 micrograms per cubic meter and the action level of 25 micrograms per cubic meter.
The final rule
is written as two standards, one for construction and one for general industry
and maritime.
Employers covered by the construction standard have until June
23, 2017 to comply with most requirements. Employers covered by the general
industry and maritime standard have until June 23, 2018 to comply with
most requirements; additional time is provided to offer medical exams to some
workers and for hydraulic fracturing employers to install dust controls to meet
the new exposure limit.
